| 摘 要： | 利用非线性热力耦合有限元方法,对浇铸过程中结晶辊辊套的温度场分布进行了研究,并同时计算出了结晶辊的热变形.给出了浇铸稳定阶段的结晶辊温度场分布和热变形规律;分析了浇铸速度对结晶辊温度场和热变形的影响.通过分析得出,在浇铸稳定阶段结晶辊温度只在表层区域发生周期性变化,内部保持基本稳定,浇铸速度越低,周期性变化幅度越大.

| Abstract: | Nonlinear thermal coupling FEM was used to investigate the temperature field and thermal deformation of roll sleeve during twin-roll strip casting. The distribution disciplines of casting roll temperature and hot deformation were figured out in the steady casting stage. The influence of casting velocity on the distribution disciplines of casting roll temperature and hot deformation was analyzed. It is concluded that during the steady casting stage, the casting roll temperature only fluctuated on the surface of the casting roll ; however at the core, the temperature was fairly stable. The lower the casting velocity, the larger fluctuation amplitude was. |
